So I love what if stories and will play them out all day long in my head! Like all day! But... I'm wondering... what started this curiosity?

I honestly think one of two things would happen with me... mostly depending on the dude's size or their numbers...

1: Go ape on the dude
2: Freeze at first... then get pissed at my iPhone for not loading the camera fast enough... then hop in my car... follow the guy until we get to a good spot where the sticky bridgestones and all 400+ horsepower can deliver a solid hit and push off a bridge or into an oncoming semi... then go ape. It's merely the principle.

 

A guy either on this forum or Another posted something about how his new stang got keyed and he couldn't do anything about it, so I just ask the curiosity question, what if you saw the crime happen in action.
I honestly believe in today's society, if I went all "ape" on the guy like you said, The other guy would be the victim. And not me

 

It really depends on the state and the individual state's criminal laws, not civil laws (that's a whole different ball game). In the south if you mess with someone's car, it's basically a 'freebie' to knock the criminal on his a$$ when he's destroying your personal property. Even if you were charged with a misdemeanor by an aggressive prosecutor (not likely) very few juries would convict if you simply stated, "The guy was destroying my car. He wouldn't stop." Now if it was a foreign car, you might get convicted.

 

In a nut shell. My first thought is who will go my bail. Because as we say in the south, somebody's fixin' to get an a$$ whoopin'.
